Question

Two numbers are in the ratio 3: 4. and their L.C.M. is 120, Find their sum

Answer 1

Answer:

Solution: The two numbers are, say, 3x and 4x, Their HCF = x and their LCM = 120. Or. 3*4*x = 12x = 120. Thus, x = 10

Answer 2

Answer:

hey mate here is your answer

Step-by-step explanation:

Let's the smaller number is 3x and greater number is 4x. Then their HCF(Highest Common Factor) will be x. Now we know that:

Product of two number = (HCF * LCM) of the two number

> 3x * 4x = 120 *x

> 12x^2 = 120x

> x^2 = 10x

> x^2 - 10x =0

Solving above quadratic equation, we get:

x = 10, 0

Since 0 is not acceptable solution. So

x = 10

Greater number 4x = 40

thank you have a great day ahead
